red lentil plots

Agronomic practices for red lentil in Alberta

High lentil productivity was attained in all major soil zones and agroclimatic zones in Alberta. Plant stand density, inoculation, nitrogen management, and weed control recommendations were found to be similar to Saskatchewan. Field trials were conducted at five locations over four years from 2012 through…

Stubble options for winter wheat

Barley silage and pea stubbles were identified as high-yielding alternatives with higher protein and greater stability compared to canola stubble in the Black soil zone. Barley grain stubble was identified as intermediate stubble option while oat stubble was a poor option. Research was conducted to…

Winter wheat stand establishment strategies

Two research studies investigated best management practices for winter wheat stand establishment at 26 sites over three years across western Canada. A strong, integrated agronomic system with high seed rate near 40 plants per square foot, a dual fungicide/insecticide seed treatment, and vigorous seed provided…

Frost tolerance of faba bean varieties

Tannin-containing faba bean varieties had less frost-damaged seed after a frost event compared to zero-tannin varieties. Yield and Thousand Seed Weight (TSW) declined with increasing frost damage for both variety types. Ten faba bean varieties were assessed after a frost event that occurred during the…

Oat seed size trial

Large oat seed improves emergence, vigour and yield

Seeding large seeded oats improved early season oat biomass by 16% and 29% at two locations in eastern Saskatchewan. Large seeded oats also improved wild oat competition and resulted in 4 days earlier maturity. Yield was 8% higher at one site with large seed. Field…

Inter-row pea

Inter-row seeding into wheat stubble improves field pea standability

Inter-row seeding field pea into 8 to 12 inch (20 to 30 cm) tall wheat stubble significantly improved standability between 6 to 23% when lodging occurred, and would be a low cost method of improving pea harvestability. The three plant growth regulators compared were of…

Replace fallow with pulses to improve water- and N-use efficiency

In a 3-year crop rotation, replacing summerfallow with a pulse crop increased total grain production by 35.5%, improved protein yield by 51%, and enhanced fertilizer-N use efficiency by 33%. A 3-year crop sequence study was repeated five times (five cycles) from 2005 to 2011 at…

Higher canola and wheat yields with diverse rotations

Averaged over 6 years from 2010 to 2015, growing canola in rotation with other crops produced 19.4% (9.4 bu/ac) higher yield over continuous canola. Wheat yields were 4.7 bu/ac (7.2%) higher than continuous wheat. When a rotation included pea once every three years, a saving…

feed barley plots

9.3% higher feed barley yield with advanced agronomic practices

Research in Alberta found that advanced agronomic practices, including supplemental post-emergent nitrogen (N) fertilizer, a growth regulator, and dual foliar fungicide applications, contributed to higher feed barley yield when growing season precipitation was not limiting. Combined, the advanced agronomic practices produced an average of 9.3%…

canola field blooming

Up to 32% higher yield with uniform canola stand establishment

Spatially uniform plant stands increased canola yield by up to 32 per cent at low-yielding sites and by up to 21 per cent at high yielding sites compared to non-uniform plant stands. Research by Agriculture and Agri-Food Canada research scientist Yantai Gan shows the importance…
